Using Tomcat Websockets with GWT

Hi,

after installing Tomcat, I had a look on the installed examples.
There was a websocket example, a simple chat.

I tried to implement it on my GWT project but I couldnt get it working.

Thats what I did:
1) I copied classes from the example into my gwt server directory:
ChatWebSocketServlet.java (extends WebSocketServlet)
HTMLfilter(does nothing special)

2) Include missing jars into my build path (tomcat-coyote.jar , catalina, tomcat-juli.jar, tomcat-util.jar)

3) Added the following to my web.xml:
      <servlet>
        <servlet-name>wsChat</servlet-name>
        <servlet-class>de.mash.project.server.ChatWebSocketServlet</servlet-class>
    </servlet>
    <servlet-mapping>
        <servlet-name>wsChat</servlet-name>
        <url-pattern>/Mash</url-pattern>
    </servlet-mapping>


4) Implemented the JS-Code from here to my html page.
I changed the following to fit my needs:
Changed
Chat.connect('ws://' + window.location.host + '/examples/websocket/chat');
to
Chat.connect('ws://' + window.location.host + '/Mash');
in the JS Code.

The problem is, that the connect()-Method doesnt work, and I cant get a socket (I end up in the JS Chat.onerror()-Method).

Im still using the Build-In Jetty for debugging, so I dont got any meaningful error so far.
The one I get from Console is mentioned below. (But its jetty, so Iam not expecting it to work).

I Debuged as Webapp (on external Server):
Then I choose my projects war-folder in apache webapp folder: But didnt got any errormsg in my console log.
Is this the proper way to use tomcat for debugging?

So...
Iam not sure if there is a misstake in my web.xml, a bad connection string on the connect()-Method,
or if Iam totally wrong and its not that easy to get it running...

Any advice, help, suggestions are appreciated.

Regards,
Manuel
